Description

The bundled "cli.js" of the Claude Agent SDK does not seem to extract MCP Server Instructions and including them in the system prompt for complex workflows. Surprisingly Claude Code does.

## Versions compared:

"@anthropic-ai/claude-agent-sdk": "^0.2.39",
"@anthropic-ai/claude-code": "^2.1.39"

## Why is it needed?

- Server Instructions are excellent for advanced workflows as it gives the server developers a chance to describe the MCP server tools in a bird's eye view, indicating different pathways the agent can take rather than letting the agent implicitly understand the overall picture from tool descriptions.
